> In Poland, workers say they were told by their line managers and HR that they were underperforming and would be terminated if they didn’t leave voluntarily. But in Portugal mutual agreements stated that dismissals were a result of a reduction of 40 per cent in the group’s activity and a 30 per cent excess in staff numbers. By getting employees to voluntarily leave, Revolut has avoided launching a group redundancy consultation, that, among other things would give employees the right to severance payments and the chance to be offered alternative roles within the company. “[Mutual agreement] is better for Revolut because they can’t go to labour court [employment tribunal],” says the source from the HR department. “The way they prepare the terminations are so bad that if someone would go to court Revolut would lose,” the source claims.
